sinter making with micro fine iron pre

The Sintering Process of Iron Ore Fines IspatGuru

The process of sintering is basically a pre-treatment process step during iron making to produce charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes (collected dusts, sludge and mill scale etc.).

Sintering - Wikipedia

  

2019-9-28  Sintering or frittage is the process of compacting and forming a solid mass of material by heat[1] or pressure[2] without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, , and other materials. The atoms in the materials diffuse across the
